Aged Cheddar Grilled Cheese

1. Preheat oven to 400 F.

2. On a work surface, lay out 4 slices of bread. Spread 1 tbsp of caramelized onion relish on each. Top with sliced pears and cheddar cheese. Sprinkle each sandwich with thyme, salt, and pepper. Top with remaining 4 slices of bread.

3. Whisk together eggs and buttermilk. Pour into a shallow dish and soak sandwiches in a single layer, turning once.

4. In a skillet heat 1 tbsp of butter over medium high heat. Add 2 sandwiches and cook until golden brown, about 2 minutes per side. Cook remaining sandwiches, adding more butter as needed. Transfer sandwiches onto baking sheet and bake in preheated oven for 5-8 minutes, or until cheese has melted.

Caramelized Onion Relish

1. In a medium pot, melt butter until foam subsides. Add onions and cook over low to medium heat until they are very soft, 10-15 minutes.

2. Add sugar and apple cider vinegar and cook gently until onions are golden brown, stirring frequently, another 10-15 minutes.

French Onion Soup

1. In a medium sized, heavy bottomed pot melt butter over medium heat. Add onions, salt, bay leaves and thyme. Cook until onions are softened and start to colour. Reduce heat to medium-low and continue cooking until onions are very soft and are a dark golden brown, about 45 minutes in total.

2. Add sherry and brandy and allow liquid to reduce slightly, 2-3 minutes. Add beef stock and continue to simmer for another 5-7 minutes. Season to taste with salt and pepper.

3. To prepare croutons, preheat oven to 350 F. Lightly brush challah slices with olive oil and season each side with salt. Toast in preheated oven until lightly golden, 2-3 minutes per side.

4. To serve soup, preheat broiler. Bring soup to a simmer. Ladle soup into 4 ovenproof bowls, leaving ½ inch at top. Place croutons on top of soup. Top with cheese. Broil until the cheese is melted and bubbling.

Herbed Mustard Dip

1. In a small bowl, mix all ingredients until well blended.
